provision of a cultivator which embodies aV plurality of shovels and a disk gang at the` Vrear of the shovels operating to throw the jsoil loosened by the shovels around the plants. i

A still further object of the invention resides in the provision of j a` cultivator in which the disk gang may be adjusted bodily in avertical direction and also bodily in a horizontal direction and in addition adjusted at different angles to the longitudinal axis of the machine. j

Another object of the invention resides in providingmeans whereby the disk gang may be adjusted so that one end thereof will lbe disposed at a greater elevation than the other end.

With the above and other objects in view the invention consists in the details of construction and in the arrangement and com'- bination of parts to be hereinafter more fully described and particularly pointed out in the appended claims.

In describing the invention in detail reference will be `had to the accompanying drawings wherein like characters of Areference denote corresponding parts in `the severalviews, and. in whichj Figure 1"is a plan view of a cultiva't-or constructed in accordance with the invention; Fig. 2, a side `view thereof; Fig. 3, a rear view of the cultivator; Fig. 4', a section on the line JE- 4 of Fig. 1; Fig. 5,. a 'section of travel from what is shown in Fig. `1; Fig. 8, a partial side view showing` the disk gang bodily adjusted upwardly'from what is shown in Fig. 2; Fig. 9, a rear view show-l ing the gang adjusted so as to dispose one end thereof at a greater elevation than the CULTIVATOR.

other end, and Fig. 10, a detail perspective View partly in section of one of the shovels.

Referring to the drawings the cultivator is shown as comprising a frame A whichr includes side members 15 and 16 theforward ends of which are contracted and connected by bolts 17, a block 18 being interposed between the forward end of said side members before the bolts 17 are applied. The side members 15 and 16 are connected at their i rear ends by a cross member 19 and intermediate their ends by a cross member 20. Ihese cross members 19 and 20 are in turn connected by a longitudinal beam 21. Secured to the side'inembers 15 and 16 and the longitudinal beam 21 are clamping straps 22 which serve to hold the shovel standards 28 to the frame A. It will be noted that the strap 22 secured to the side memberl is disposed relatively near the cross beam 20, while the strap 22 secured to the longitudinal beam 21 is at the rear of the strap secured to the side member 15,

.while the strap `22 secured tothe side member 16 is at the rear of the strap 22 secured to the longitudinal beam 21. By this construction it will be apparent that by releasing one of the bolts of any of the straps 22 the standard 23 held thereby `may be adjusted vertically as desired. The lower ends of the standards 23 terminate in a reduced stem 24 on which is engaged a cla1nping collar 25 carried by a shovel 26. By releasing the `clamping collar 25 it will be apparent that the shovel 26 can be rotated on the stem 24 whereby the shovel may be positioned to throw the soil a greater or less dist-ance from the plants to be cultivated.

Pivoted to the rear endsiof the side members 15 and 16 are the free ends ofthe arms 27 and 28 of an approximatelyU-shaped supplemental frame B. The arm 27 of this frame B is looped to form a vertical bearing 29 and the arm 28 `of this frame is curved so as to lie concentric" to the bearing 29 for a purpose that will. presently appear. The arms 27 and 28 `are each extended beyond their pivotal connectionswith the side members 15 and 16 and terminate inenlarged portions 30 respectively provided with arcuate slots 31. Engaged through theseslots 31 are bolts 32carried respectively by sidev members 15 and 16. By loosening the bolts .B2 it will be apparent that the rear end of vthe frame B may be raised and lowered and when disposed in the' desired adjustment may be locked against movementby'o-perating the bolts 32. Slidably mounted on the arm 2S of the frame B is a block 33 which carries a binding screw 34 adapted to be operated to impinge against the arm 28to secure side blo-ck against sliding movement.

. The lower end of the block 33 vis provided lof the gang by means of a spring 55 one with a passage 35 for a purpose that will presently appear.

Mounted in the bearing 29 is a bolt 36 upon which is rotatably mounted one end of a beam 37 the other end of said beam being slidably engaged in the passage 35 of the block 33. The end of the beam 37 adjacent the bearing 29 is provided with a plurality of bolt openings 38 through which the bolt 36 is adapted to be interchangeably engaged. By thus interchangeably engaging the bolt 36 in the openings 38 the beam 37 can be adjusted transversely of the frame A. The disk gang of the cultivator is indicated generally at C and is supported from the beam 37 by means of U-shaped brackets D and E. The arms of the bracket D are indicated at 39 and 40 and the free ends of these arms are disposed in embracing relation to the beam 37 and pivotally connected to the latter by means of a bolt 41. A block 42 is interposed between the arms 39 and 40 between-the beams 37 and the axles of the disk gang C. This block 42 serves to strengthen the bracket D." ...The arms of the brackets vE are indicatedv at 43 and 44 respectively and are disposed in embracing relation to the beam 37. The free'ends of the arms 43 and 44 are provided respectively with arcuate slots 45 through which is engaged a bolt 46, said bolt also passing through the beam 37. Engaged through the free end of the arms 43 and 44 above the beam 37 is a bolt 47 to which is pivotally connected the ends of links 48 and 49. The other ends of these links 4S and 49 are pivotally connected to the bolt 41. A block V50 is interposed between the arms 43 and 44 for the purpose of strengthening the bracket E. By this construction it will be apparent that upon loosening the bolt 46 the left hand end of the disk gang may be elevated and lowered Aand locked in a desired adjustment through the medium of the bolt 46. Carried by and projecting rearwardly from the brackets D and E are guide members 5l and 52 respectively in which is slidably mounted for movement transversely of the disk gang a cleaner carrying bar 53 upon which are fixed disk cleaners 54 corresponding in number `to the number or disks in the gang C; These vdisk cleaners 54 arey normally held in operative relation to respective disks end of which bears against the shank of one of the cleaners 54 and the other end against the guide member 52. Pivoted on the bar 53 is a cam 56 which when moved to a position longitudinally of the bar 53 will engage the guide member 52 and slide the bar 53 in said guide members against the influence of the spring 55 and thus draw the cleaners 54 away from respective disks of the gang. lVhen the lever 56 is moved to lie at an angle to the bar 53 saidbar is released to the influence of the spring 55 and moved by thelatter so as to carry the cleaners 54 into coperative relation with respective disks of the gang.

From the foregoingdescription taken in connection with the accompanying drawings it will be apparent that the disk gang C may be readily adjusted in various ways to meet varying conditions, such adjustment in response to changes in conditions serving to maintain the cultivator at a maximum efiiciency with the result that a vmachine of the character described willbe able to per-V form a maximum amount of workl 1n a given space of time without any reorganization of' parts whatsoever.

(What I claim is:-

l. In a cultivator the combination of a frame, a block slidable onsaid frame and having a passage therethrough,l a beam pivoted to the frame for movement in a horizontal plane and engaged through the passage in the block, a bracket pivoted to the beam, a second bracket havingan adjustable 'sliding connection with the beam, and a disk gang supported by said brackets.

2. In a cultivator the `combination 'of a l main frame, a supplemental frame adjustably pivoted on the 'main frame for movement in a vertical plane a beam 'having one end pivotally supported upon the supplemental frame, and its other end slidably engaged with one side of the supplemental frame, said side of the supplemental frame being curved concentrically 'with respect to the pivot of the beam, means for locking the free end of the beam against slidingl movement on the frame, 'and a disk gang supported from the beam.'

In testimony whereof, Iatx my signature, vin the presence oftwoV witnesses.
